Name of the topic you picked:Natural Selection

Fact 1:For example, the peppered moth exists in both light and dark colors in the United kingdom, but during the industrial many of the trees on which the moths rested became blackened by soot, giving the dark-colored moths an advantage in hiding from predators.



Fact 2:The concept of natural selection predates the understanding of genetics, the mechanism of heredity for all known life forms. In modern terms, selection acts on an organism's phenotype, or observable characteristics, but it is the organism's genetic make-up or genotype that is inherited.



Fact 3:The term natural selection has slightly different definitions in different contexts. It is most often defined to operate on heritable traits, because these are the traits that directly participate in evolution. However, natural selection is "blind" in the sense that changes in phenotype (physical and behavioral characteristics) can give a reproductive advantage regardless of whether or not the trait is heritable (non heritable traits can be the result of environmental factors or the life experience of the organism).

Fact 4:These surviving bacteria will then reproduce again, producing the next generation. Due to the elimination of the maladapted individuals in the past generation, this population contains more bacteria that have some resistance against the antibiotic. At the same time, new mutations occur, contributing new genetic variation to the existing genetic variation. Spontaneous mutations are very rare, and advantageous mutations are even rarer. However, populations of bacteria are large enough that a few individuals will have beneficial mutations. If a new mutation reduces their susceptibility to an antibiotic, these individuals are more likely to survive when next confronted with that antibiotic.
Fact 5:

Texas Endangered Species

Habitat loss. All animals and plants depend on the place they live (habitat) for food,
water, shelter and living space. The plants and animals within a habitat also depend on each
other. They interact in many ways. Environmental contamination. The use of some pesticides, fertilizers and chemicals led to a decline of certain species, such as bald eagles and peregrine falcons.To endangered is to To expose to harm or danger.I dint knew that a lot of this animals are getting harmed and they are being in danger
